SPECIFICATION forming part of Petters Patent No. 287,641, dated October 30, 1883, pplicaiion Yfiled June 1,1883. l(No model To all w/wm, it may concern:

Be it known that I, A. FLOYD DELAFIELD, of Noroton, in the county otl Fairfield and State of Connecticut, have invented a new and Improved Electric Batt-cry, ofy which the following is a full, clear, and exact descrip- This inventionrelates to that class of batteries in which the elements are fixed` and the cells are adapted to be raised or lowered.

The object of my invention is to provide means for easily and 'rapidlyiilling all the cells with the excitingdiqnid, and also to provide means for preventing the surfaces ot' the cells from coming in contact with each other, thereby preventing undue weakening of the battery.

The invention consists in a box forreceiv- Aing the cells, which box is .provided at the ends with pintles or trunnionsresting ona frame, thus permitting theV cell-box to be tilted or inclined, so that the superfluous liquid can run from all the cells at the Sametime, and the level' of the liquid will be the same in all cells. l

The invention also consistsl in a cell provided with aboss pn each side and on the bot i `of my improved battery on line x al, Fig. `2.

Fig. 2 .is across-sectional elevation of the same on line 1/ y, Eig-1. Fi g. 3 is a perspective view of the cell. y

' Any suitable number of cells, A, are placed side by side in a boxv or framed case, B, provided at each end with a pintle, pivot," or trimnion, C, arranged at the middle or at the sides,

which pintles or pivots rest upon a frame, D, snrrouiulingvy the top of the box or frameB, which frame D must be so much" larger than the frame B that the latter can easily be swung within the frame D. The frame D is suspendedirom cords E, passed over ahoisting-drum, F, provided with a crank-handle, G; or the frameD can bc connected with any other suitable devices for raising it. The battery plates or elements H are held on cross-bars I of the frame-work on the box J, adapted to receive the box B.

The cells A, whiclrcan be made of glass, earthenware, hard rubber, &c., are provided on the outer surface of the bottom, each end and each side, witha boss or projectiom a.

It' a series of cells are placed in a box, D,

.the entire surfaces ofthe cells cannot come in contact with each other, nor with the sides 'ot' the box B, as only the bosses can come in c ontact with each other `or with the sides of the bon.v Thereby' weakening of the battery through' conduction betweeny the cells is prevented. The exciting-liquid is poured into box J, and it flows over the edges of the cells and iills the same. AThen the. frame or box B is swung on its trunnions on pivots C until it is v:more or less inclined transversely. The snrplusI of exciting-liquid will th'en flow over the tops of the cells into box J and will collect .0n thebottom of the same, andcan be drawn off; As all thecells will be inclined or tilt-ed at the same angle, the level of the liquid will be the same in all the cells. i

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-

1. In an electric battery, die combinatimi,

`with a box for receiving the cells, of pivots,

pintles, or trunnions projecting from the ends of the box, and of a frame surrounding the box containing the cells, for raising the cells from the containing -box, on which lat-ter frame the trunnions or Vpintles rest, substantially as herein` shown and described, and for the purpose set forth.

2. In an electric battery, the combination, with a box f or receiving the cells, of pintles or trunnions projecting from the ends of the box, afranie surrounding the box containing the cells, and adapted to act as pivotal points for the cell-box, and of devices for raising andv lowering the said frame, substantiallyas herein shown and described, and for the purpose set forth.

'3.111 an electric battery, thc combination, with a box for receiving the cells, ot` pintles or trunnions projecting 'from the ends of the said box, a frame surrounding the cell-box, and an additional box for receiving the cell- IOO box and the frame surrounding it, so as't-o 5.
